Philips 18-inch T12 Fluorescent Tube - 20W | 6500K | G13 | Pack of 30

The Philips 18 inch T12 Fluorescent Tube, model F20T12/D/ALTO (273284), is specified at 20W, 6500K. Use this model in the corresponding T12 lamp system where the fixture retains replaceable tubes, for example an office troffer or a service-area strip. This 6500K version has a cooler white appearance, which can suit the break room or work area when a daylight-toned scheme is preferred. This listing supplies a pack of 30 units of this model.

The 24-inch format identifies the lamp position; its 20W rating must also suit the selected operating arrangement. The G13 base must correspond to the installed lampholders. This model remains a fluorescent lamp: the fixture needs a ballast rated for its lamp type and wattage, with the specified number of lamps.

Buying tip: Match the lamp designation and pin arrangement to the existing ballast. Measure the installed lamp before ordering a different length.
